To all whom it concern:

Be it known that citizen of the v United States, residing at Rochester,in the county of Monroe and State of New York, have invented certain newand useful Improvements in; Check Writers, of which the following is aspecification.

This invention relates generally to printing machines, and hasparticular reference to what are commonly known as check writers becauseof the fact that they are used mainly to write in the amounts. of bankchecks and similar instruments.

One'object of the invention is to provide a satisfactory mechanism,separate from, but operating adjacent to the printing type and platen,to shred, break or otherwise disrupt the fibre of the material prlntedupon so thatthe ink used in printin may more readily penetrate themateria and thereby increase the difficultyvof erasing or altering theinscription.

Another object is to provide a mechanism I such as just described, whichwill have certain advanta es over prior devices of the kind. One avantage isthat the improved mechanism is actuated to disrupt the paperor other material directly and positively by movement of the operatinghandle or corresponding prime mover of the machine. As

a result, when the improvement is ap lied to machines constructed toprint by ro ling engagement of the type and platen the mechanism isdriven in a fixed relation to the moving printing elements, and thepaper is never subjected to a grinding action by the type and platen, orto any other strain or stress which might cause it 'to be torn orotherwise improperly mutilated.

With the above and incidental objects in,

view, the invention consists in the novel combination and arrangement ofparts, a preferred form of embodiment of which is hereinafter describedwith reference to the drawings accompanying and forming a part of thespecification and the features of novelty of which are pointed out inthe appended claims.

Fig. 5 is a section on the line Fig. 1.

Fig. 6 is a top plan viewof the platen-and paper-disrupting devices andtheir operating connections.

The machine to which an embodiment of the invention is shown applied inthe accompanymg drawings is of a type well known on the market and whichis shown and de- I scribed in U. Letters Patent No. 1,138 330, issuedMay 4, 1915, to L. M. Todd and G. Tiefel. Such machines have a typecarrier provided with word type forms of difi'erent lengths, and arotary rinting platen. The type carrier is first adjusted to set the desired word type form opposite the platen, after which a main-operatingmechanism is actuated to actuate the type carrier and thereby effect arolling printing engagement of the type and platen. The co-operatinfaces of the type and platen are. corrugated or otherwise roughened, andco-operate to break or disrupt the fibres of the paper as an incident toprinting.-

In the form the present invention takes when applied to a machine of theTodd and Tiefeltype the faces of the type and platen may be left smooth,and the shredding or disrupting action upon the aper is erformed by anauxiliary mec anism w ich comprises two differentially rotatablerollers, one above and the other below. the work, and havin theirwork-enga 'ng faces corrugated or ot erwise roughene to break or loosenthe fibres as the work passes between them. Preferably these rollers arepositioned to do their work in advanceof the printin A dierentialmechanism is provided for driving one or the other of the rollers,preferably the upper one, directlyby movement of the main operatingmechanism to extents corresponding with the lengths of'the wordsprinted; This diflerential mechanism is controlled to determine theextent of movement of the driven roller by the same mechanism as is usedin effecting the above-mentioned movement of the type carrier to setthevarious word type forms in printing relation with the platen.

In the form shown the differential mecha-' nism comprises a set oftoothed elements, one for each word type form, graduated to correspondwith the lengths of the-associated type forms. Common tothis set oftoothed work-breaking roller.

elements is a pinion or gear acting through suitable connections todrive the upper The construction is such thatwhenthe type' selectingmecha-. nism has been operated to set the desired word type form inposition to co-operate with the platen, the corresponding toothedelement will be in position to co-operate with the driven gear.. Thesubsequent operation of the machine to efi'ect enga ement .of the typeand platen to print the esired word'will cause the toothed element toact upon the driven gear and turn it .a distance corresponding to thelength of the t e. ti' nsmitted through the connections mentioned to thework-breaking roller.

The Todd and Tiefel machine has a central shaft '10 journalled at itsends in'the case 11 of. the machine. Secured to the shaft is a gear 12,Fig. 2, meshing with a pinion 13 secured to the inner end of a shortshaft 14 journalled in a boss 15, Fig.

1, on the'casing'. Attached to the outer end of the shaft 14 is a handle16 by means of ,Which the shaft 14 may be turned. This movement oftheshaft 14 is transmitted by the gears 13 and 12 to the shaft 10 and asthe gears 13 and 12 are of the same size each turn of the handle 16 willresult in a "complete rotation of the shaft 10. A type carrier 17 issplined upon the shaft 10 so that it may be adjusted to differentpositions along the shaft but will turn with the shaft when the latteris rotated. The face of the type carrier is rovided with a number ofword type orms 18 of various len hs. Y

or the purpose of moving the carrier to difierent positions on theyshaft there is provided a yoke 19, the ends of which are looseupon andsurround theshaft 10 so that if the yoke is moved endwise of the shaftthe type carrier is carried along. ,Near one end the oke is providedwith a handle 21, Fig. 3, integral with which is a pointer 22co-operating with. an index plate 23, Fig. 1, to guide the operator inadjusting; the yoke and thereby the type carrierto ilferent printingpositions. 1

Under the typev carrier is a laten wheel or disc 24, Figs. 3 and 6,'rotatab y supported between arms of a yoke 25 secured to a shaft 26journalledat one end in the casing and at the other end in a cross bar28 integral with the casing. Secured to the end of the shaft 26 is anarm 31, Fig. 5, having its up per end formed to co-operate with a cam 32secured to theshaft 10. The configuration of the cam 32 is such thatwhen the shaft -10 is rotated clockwise, Fig. 5, the leverv 31 and shaft26 will be rocked in the same direction against the tension of a spring33. This will cause the platen 24 This movement 'of the gear will be tobe swung into the-path of travel of the type form which has been set inprinting re ati on to the platen and held stationary long enough toco-operate with the lon est the material in advance of the printing.

These rollers are positioned oneabove and one below the work-receivingslot and are separable to permit insertion of the work.

Before any word can be printed the rollers are brought together to actupon the paper, and remain in that relation until. after the printing ofthe desired inscription is completed and the rollers separated to permitremoval of the paper.

The upper one of the rollers is designated by the numeral 35, Fi 3, andis secured to a shaft 36, (see also Fi The lower roller 38, Figs. 3and'6, isloose upon a rod supported between the side arms of a yoke 39attached to a rock shaft 40. This rock shaft is formed atits forwardend, first toward the center line of the mas chine and then upward, theupwardly ex tending end being beveled as shown at 41, Fig. 2, toco-operate with the surface 42 on the type selecting yoke- 19.. When thepipe selecting'mechanism is operated to set -e on t e selecting dial,the surface 42 of th type selecting yoke will act upon the end 0 the rod40 to rock the rod counter-clockwise, Fig. 3, against the tension of aspring (not shown), thereby lowering the roller 38 to permit insertionof the paper. When the pointer 22 is moved to any other position thetension of the spring is released and returns the roller 38 intoengagement with the roller 35.

The'fa'ees of the rollers 35. and 38 may be corrugated or roughened,according to any desired plan so that they will cooperate to disrupt thepaper and permit the ready peng. 1) supported b brackets 37 attachedto-the machine casd:

ointer 22 opposite the word Release etration oflthe ink. In order toinsure firm engagement of the rollers there-is provided genomes thepaper in the line in which the payeesname is usually written on a check.

The mechanism for difierentially driving the roller 35, and, of course,the roller 53,

distances corresponding to the length of theword rinted, comprises a setof partial gears esignated agenerally by the numeral 54. These partigearsare fast upon a shaft 55, journaled at its ends in arms 56extending from the end members ofthe type selecting oke 19. A stifieningbar or'rod .57 extends thru all of the toothed elelments 54. I

Rotation of the partial-gears or elements 54 is efiected when the handle16 is turned to rotate the ty e carrier 17 into engagement with the aten24 to print. For t is purpose there 15 provided a gear 61 rigid with thetype earner meshing with a pin on 62 rotatably mounted on the yoke 19and which in turn meshes with a gear 63 rigid with the shaft 55 andelements 54. It is apparent that at each-turn of the handle 16 the shaft55 and the parts thereon will be rotated. I V I A shaft 64 rotatablymounted 'above the toothed elements 54 has fastened thereto a smallgear65. Near the other end ofthe shaft 64 is another gear 66 meshing with anintermediate gear 67 which in turn meshes with a gear 68 loose upon thecentral shaft 10. The teeth or thegear 68 are atall times in engagementwith theteeth of a smaller gear 69 secured to the shaft 36 prevlouslymentioned.

The toothed elements 54 are in alinement with and each with a singleexception has a number of teeth corresponding to the lengths oftheassociated type forms 18.-

When the type selecting yoke 19 is moved to position the desired typeform 18 in opcrating relation with the platen 24, the cor respondingtoothed element 54 will be set in alinement with the gear 65. Subsequentoperation of the handle 16 to effect printing rotation of the t ecarrier will cause the shaft 64 to be driven an extent determined by thenumber of teeth on the positioned element 54.

As stated above, there is one exception to having the number of teeth onthe elements 54 correspond with the lengths of the associated t e forms.This exception is found in the e ement 541 in almement with the t peform tor printingthe word Exactly. n operating the machine shown in thedrawings the word Exactly is printed first, with the words representingthe amount following in the usual order. The gear 541 at the Exactlyposition has a toothed portion. considerably longer than being such thatalmost immediately after the operation of the handle 16 is begun theteeth of the ear 541 will begin to rotate the shaft 35 an roller 35. Asa consequence, the paper will be disrupted and fed tar GllOllgll for thedisrupted surface to be in position to 'recelve the impression by thetiling the Exactly type form engages the p a en.

The gearing above described is so proportioned that the periphery of theroller 35' and, of course, the associated roller 52, will move at thesame peripheral speed as the type, when the type pass across the platen24. As a result of this construction, the work of the rollers 35 and 38is erformed in proper time relation with the printing action of the typeand platen, and the aper is relieved fromany strain or stress etween theprmtlng polnt and the point where it is'disrupted. 1

j In order to insure holding the differential gearing in proper positionto be en a p d b the teeth on the different elements hi her-Z isprovided a means forlockingthe shaft 36 against movement betweenprinting operations. As shown in Fig. 5, the arm 31 previously mentionedis provided with an extension 71, carrying a stud 72 normally inengagement with the teeth of the gear 69. When the arm 31 is rocked bythe cam 32, as previously described, the stud 72 will be disengaged fromthe gear 69, thereby freeing the gear and connected parts for rotation.When the cam allows the arm 31 to return to its normal position, thestud will re-engage the gear to aline and hold the various parts inproper position ready for thenext operation. I

The inking mechanism may, of course, be of any suitable form, but in thedrawings it is shown as comprising rollers 73 and 731, supplied with inkof one color, vand rollers 74 and 741 supplied with ink of a differentcolor. As the type carrier 17 isrotated, the type contact these rollersto replenish the supply of ink on the type.

In describing the invention it has incidentally been necessary to pointoutthe different steps of the operation, so it is believed that thestatement of the operation usual at this oint may be omitted.
